Title: Manufacture of metal mold for molding of consumable casting pattern
Inventor: MORITA YASUJI
IPC: C25D1/02
Filed: 1981-10-29
Abstract: PURPOSE:To obtain metal molds of a light weight, large cooling capacity and semipermanent durability for molding of consumable casting patterns by electrodepositing  copper on matrices for electroforming which is formed to prescribed shapes. CONSTITUTION:In the case of making metal molds for molding of consumable casting  pattern 1 for, for example, turbine blades, a set of upper and lower matrices 2 are  formed beforehand in conformity with the upper and lower half parts which are parted  and formed to upper and lower parts at the plane C-C of the pattern 1. The pattern 2  consists of a projecting part 2a (a recess with the lower half part) of the shape conforming to the upper half part of the pattern 1 and flat parts 2b which are continuous  with said part and are provided on at least 3 sides of the part 2a. The matrices 2 are  made of gypsum, reinforced plastics, Al castings, etc. After the projecting part 2a (or  recess) and the flat parts 2b of the matrix 2 are subjected to a conducting treatment,  the matrix is dipped together with a copper material for consumable electrodes into a copper plating bath and electricity is conducted between the electrode copper materials. If the copper layer on the surface of the resultant matrices 2 are stripped from the matrices 2, intended shell-like copper metal molds 3 are obtained. The top and  bottom molds are joined.

Title: Production of disk substrate and die unit
Inventor: SASA TAKESHI
IPC: G11B5/84
Filed: 1998-06-22
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of projecting parts on the surface due to fine foreign matter by forming a pair of metallic dies used for the injection molding of a resin material from a material having a specific heat conductivity to suppress the formation of a skin layer on a part in contact with the dies. SOLUTION: The molten resin material is filled into a cavity 14 formed from the fixed side die 11, the movable side die 12 and an outer peripheral ring 13 and cured. The material such as zirconium oxide having <0.03 cal/ cm.sec. deg.C heat conductivity is used for a pair of the dies. As a result, the molten resin material is prevented from making the curing rate slow and from being rapidly cooled on a part in contact with the dies to eliminate the formation of the skin layer and because the resin material is gradually cured from a part in contact with the dies, the unhardened part is uniformly existed without hardening only a part, where the foreign matter is existed, even if the fine foreign matter is incorporated, the difference of shrinkage is mitigated and the generation of the projecting part on the surface is prevented.

Filed: 1991-07-16
Abstract: PURPOSE:To save idle image processing time by providing each means for stopping the operations of driving parts such as a heater and a motor by setting a sleep mode and starting operations of these driving parts when the formation of image data is started. CONSTITUTION:A CPU 1 starts the formation of image data based on reception data to be printed from a host computer and discriminates whether the present mode is a sleeping mode or not. When it is judged as the sleeping mode by the CPU 1, the CPU 1 removes the mode, revolves a motor 8 and controls the rotational speed of a mirror 7 and a temperature so that they may be a prescribed value by turning a heater within a polygon mirror 7 on. While the control is performed, the formation of the image data is continued in parallel. When the formation is terminated, a print processing is performed for image information light. Then, when it is terminated, the sleeping mode is entered by stopping the motor 8 and the heter. Thus, idle image processing time can be saved.

Abstract: PURPOSE:To effectively work a laser beam energy and to enable laser beam machining over a wide range by the laser oscillator of a small output by projecting a laser light by converging it on the surface of the body to be worked by a converging means and removing a generated carbonized residue by air and gas blowings. CONSTITUTION:The laser light 1 emitted from a YAG pulse laser oscillator 2 is projected by converging the surface 7a of the body 7 to be worked by a converging means 13 to mark a stencil 5 mark on the surface 7a. In that case, a generated carbide remains on the surface 7a of a projected body to be worked to reduce the projection effect.

A small output will therefore do on the laser light oscillator 2 and also the range that the stencil 5 mark is well projected is enlarged.
